2 Claims.

This invention relates to a device for holding and therewith dispensinga portion of tape from a dry adhesive tape roll. The handling of suchrolls and severance of sections of tape therefrom involve considerabledifficulties and inconveniences, due to the character and nature of thismaterial.

The principal object of the invention is to provide a device for theabove purpose, which will be conveniently and economicallymanufacturable, saleable at low cost, conveniently utilizable, strong,durable, and wherewith the tape roll may be eificiently carried andsections thereof severed with ease and without loss.

Another object is to provide a dispenser of the above type which isdevoid of moving parts, which may be made entirely of plastic with aminimum bulk of such material for accommodating a given size of roll andwhich is yet inherently amply strong to withstand the strain imposed inthe tape dispensing and severing operation.

Other objects and advantages will hereinafter appear.

In the accompanying drawing:

Fig. 1 is a perspective view showing the dry adhesive tape rolldispenser, constituting the invention.

Fig. 2' is a plan view of the dispenser shown in Fig. 1.

Fig. 3 is a front elevation of the dispenser.

Fig. 4 shows a cross-sectional elevation of the dispenser, taken on line4+4 of Fig. 2.

The'dispenser I comprises a unitary integral 7 body of plastic materialhaving a base 3, and a coaxial hollow stud 4 extending upwardlytherefrom, and carrying a toothed cutter bar 5. Shoulders 1 are locatedat the ends of said cutter bar and project beyond th cuttingconformation, preferably a line of cutting teeth, as shown. The cutterbar 5 is parallel to the axis of the dispenser and its lower or root endis an integral lateral protuberance from the periphery of the base .3.Integrally with the cutter bar and preferably along the full lengththereof extends the outer end of a curved wall 2 which risesprogressively from the point l6 on and thence along the pe-' riphery ofthe base, its upper edge thus extencl with. While the height of thecutter teeth extends radially of the dispenser, the ledge 6 extendspreferably at right angles to the teeth, generally tangentially of thedispe er d inward from the cutter toward the discharge web I ll of thespool of tape. The stud 4 is adapted to receive the core 8 that carriesthe roll 9 of dry adhesive tape it, whereby said roll is capable ofrotating about said stud in an anti-clockwise direction, as viewed inthe drawing, for unrolling the tape. The top of the stud 4 is providedwith a central hole II, and a disk I2, having a diameter larger thansaid stud but preferably smaller ing along a helix I! as shown. Thecurved wall 2 thus constitutes a web binding the length of the cutterbar to the base and serves as a buttress resisting the strain applied atthe cutter bar 5 inuse of the dispenser. The device is also providedwith a rounded ledge 6 which is of substantially the length of thecutter bar 5 and is adjacent and parallel to said bar and integraltherethan that of the roll 9, carries a lug l3 which is wedginglyinsertible into and removable from the hole H, by which means the disk[2 may be mounted upon the stud 4 to thereby retain the roll againstremoval thereof from the stud 4, as showninFig.4.

In the handling of the tape roll 9, for severance of lengths of dryadhesive tape therefrom, it is vital to maintain a fragment Illa of thetape at all times away from the roll, otherwise such fragment and itsterminal accidentally adhere to the roll, rendering it diflicult andannoying to separate the former from the latter when it is desired todispense the tape from the roll. Also, for efiiciently cutting oil thelengths of tape from the roll 9 it is preferable to apply a hold uponthe tape close to the intended lineof. severance.

When it is desired to remove a length of tape from the roll, the sectionrequired is unrolled and its intended terminus is brought over to thecutter 5. The user holding the entire device with one hand then appliesthe thumb upon the tape portion lb and Dresses it against the ledge 6 ofthe device, while drawing the unrolled length of tape across the cutter5 with the other hand. The temporary adherance of the tape portion [0bto the ledge 6 aids in the fficient severance of the tape withutilization of the cutter 5, while at the same time this adheredcondition of the tape portion lllb to the ledge 6 serves to retain aleading fragment of the tape Illa away from the tape roll 9 proper,thereby at all time providing an initial unattached tape fragment Illanecessary for a succeeding removal of a subse quent tape length.

When it is desired to adhere a preliminarily ine determinate length oftape l0 upon a surface Fig. 1, the disposition ofthe rolls on thebase 8is first reversed. by lifting. olf the disk, removing the roll, andreplacingitin turned-over state about the stud I. so that theback Hidopposite adhesivlll'c of the unrolling tape now faces the ledge 6. Aportion of the tape is then unrolled and its end We is adhered to thelocation required. The dispenser may be then held in the positionillustrated in Fig. 1, with its shoulders I bearin upon the surface I4,and in this position advanced to unroll the tape until reaching thedesired place for applying the terminus of the required length of tapeto be used, whereupon the said length may be severed with the cutter 5.While thus advancing the dispenser in the described manner, theshoulders I serve to maintain the leading portion l0 of the tapeslightly away from the surface l4, thereby efficiently positioning thecutter 6 for severance of the oncoming terminus of the neededtape-length, by a slightly lateral twist of the cutter and simultaneousyanking pull of the dispenser away from the adhered tape length Illa.The shoulders I also serve to accurately align the unrolling tape lengthwith the roll 9, both for tearing ofi a section thereof and whileapplying it in the manner shown in Fig. 1.

Variations may be resorted to within the scope of the invention.

Having thus described my invention, I claim:

1. A unitary dispenser for a dry adhesive tape roll comprising a basedisk, an uprising hollow stud coaxial therewith for accommodating a taperoll thereon, an upright cutter bar rising from said base and integraltherewith, having a cutting conformation extending radially outward fromsaid base, a curved wall extending progressively upward from said basealong the periphery thereof, with its end unitary with the cutter barand of substantially the height thereof, said cutter bar having alateral ledge extending at an angle to the cutter conformation in thedirection opposed to said web.

2. A dispenser for a dry adhesive tape roll comprising a base disk, anuprising hollow stud coaxial therewith for accommodating a tape rollthereon, an upright cutter bar rising from said base having a cuttingconformation extending radially outward from said base, a curved wallextending progressively upward from said base along the peripherythereof with its end unitary with the cutter bar and of substantiallythe height thereof, said cutter bar having a lateral ledge extending atan angle to the cutter conformation in the direction opposed to saidweb, the upper and lower ends of said cutter bar having shouldersprotruding beyond the cutting conformation, said dispenser being anintegral plastic structure, said dispenser having a removable cover diskconcentric with the stud and of diameter to overlap a part of the taperoll.
